Using the Line Trigger Wait Signal with the Trigger Width Exposure Mode
When the camera is set for the trigger width exposure mode, the rise of the Line Trigger Wait signal
is based on the Exposure Overlap Time Max Abs parameter setting and on when readout of the
current line will end. This functionality is illustrated in Fig. 48.
If you are operating the camera in the trigger width exposure mode and monitor the Line Trigger
Wait signal, you can avoid overtriggering the camera by always doing the following:
 Setting the camera’s Exposure Overlap Time Max Abs parameter so that it represents the
shortest exposure time you intend to use. If the shortest intended exposure time is larger than
the maximum settable Exposure Overlap Time Max Abs parameter value, set the Exposure
Overlap Time Max Abs parameter value to its maximum.
 Making sure that your exposure time is always equal to or greater than the setting for the
Exposure Overlap Time Max Abs parameter.
 Only use the ExLSTrig signal to start exposure when the Line Trigger Wait signal is high.
